Abstract

Es betrifft ein automatisiertes Schaltgetriebe für ein Kraftfahrzeug, mit mindestens einer Getriebeeingangs- und Getriebeausgangswelle (2), auf denen Zahnräder (4,6,8,10,12,14) angeordnet sind, die zur Ausbildung unterschiedlicher Gangstufen paarweise kämmend miteinander in Eingriff stehen, wobei auf der Getriebeeingangs- und/oder Getriebeausgangswelle Synchronisiereinheiten (18,20,22) vorgesehen sind, über die eine drehfeste Verbindung von Getriebeeingangs- und/oder Getriebeausgangswelle (2) mit den Schalt- bzw. Losrädern der Zahnradpaarungen herstellbar ist, sowie mit mindestens einer Schaltstange (32), auf denen Schaltgabeln (34) gelagert sind, die in Verbindungsorgane (Schaltmuffen) der Synchronisiereinheiten (18,20,22) eingreifen, und dass zur Betätigung der Schaltgabeln ein federbelasteter Schaltschlitten (38) vorgesehen ist.It relates to an automated manual transmission for a motor vehicle, with at least one transmission input and output shaft (2) on which gears (4,6,8,10,12,14) are arranged, which mesh with each other to form different gear ratios meshing with each other , Synchronizing units (18,20,22) are provided on the transmission input and / or transmission output shaft via which a rotationally fixed connection of Getriebeeingangs- and / or transmission output shaft (2) with the shift or loose wheels of the gear pairs can be produced, and with at least one shift rod (32) on which shift forks (34) are mounted, which engage in connecting elements (shift sleeves) of the synchronizing units (18, 20, 22), and in that a spring-loaded shift carriage (38) is provided for actuating the shift forks.

Es wird vorgeschlagen, dass sowohl der Schaltschlitten (38) als auch das Schaltfederelement (52) auf der Schaltgabel (34) gelagert sind.

Figure imgaf001
It is proposed that both the shift carriage (38) and the shift spring element (52) are mounted on the shift fork (34).
